Imagine lying in bed at 1:00 a.m., watching the minutes tick by while your alarm is getting closer. You finally fall asleep, only to wake up a few hours later and start the same cycle again. After several nights like this, you may wonder whether a prescription sleep medicine such as Restoril or Lunesta could help. This is where understanding Restoril and Lunesta becomes important. This overview gives the short answer first, then the details.
Restoril is the brand name for temazepam, a benzodiazepine used to treat insomnia, while Lunesta is the brand name for eszopiclone, a hypnotic medication also used to treat insomnia. Although both medicines can help with sleep, they belong to different medication classes and have different safety considerations, side effects, interactions, and risks of dependence or withdrawal.
What Is Restoril (Temazepam)?
Restoril is the brand name for temazepam, a benzodiazepine prescribed for short-term treatment of insomnia. This section covers its class, forms and key medical points.
Drug Class and Forms
Temazepam is a benzodiazepine and a Schedule IV controlled substance in the US. Restoril is typically supplied as capsules, with strengths such as 7.5 mg, 15 mg, 22.5 mg and 30 mg. Generic temazepam is widely available.
Approved Use
In the US, temazepam is approved for the short-term treatment of insomnia, meaning difficulty falling asleep, staying asleep, or both. The label generally frames treatment in terms of days to a couple of weeks rather than months.
Key Medical Considerations
- Intermediate-acting: It stays in the body long enough to help with staying asleep, but also long enough to cause next-morning grogginess in some people.
- Boxed warnings: Benzodiazepine labels carry boxed warnings about combined use with opioids, abuse and misuse, and physical dependence with withdrawal reactions.
- Liver processing: Temazepam is cleared mainly by conjugation (glucuronidation) rather than by the CYP enzymes that many drugs rely on, so it has fewer CYP-related drug interactions than some other sedatives.
What Is Lunesta (Eszopiclone)?
Lunesta is the brand name for eszopiclone, a nonbenzodiazepine sedative-hypnotic used for insomnia. Here is what to know about its class, forms and use.
Drug Class and Forms
Eszopiclone belongs to the cyclopyrrolone group of “Z-drugs,” alongside zolpidem and zaleplon. It is a Schedule IV controlled substance in the US. Lunesta comes as tablets in 1 mg, 2 mg and 3 mg strengths, and generic eszopiclone is available.
Approved Use
Lunesta is approved for the treatment of insomnia, including trouble falling asleep and trouble staying asleep. Unlike temazepam’s short-term framing, its US label does not set a fixed maximum duration, and studies have followed people for several months. Even so, clinicians typically reassess the need for it regularly.
Key Medical Considerations
- Boxed warning for complex sleep behaviors: Sleepwalking, sleep driving and other activities done while not fully awake, sometimes with no memory afterward, have been reported. The FDA added this boxed warning to eszopiclone, zolpidem and zaleplon in 2019.
- Next-day impairment: Because of concerns about morning drowsiness, the FDA has urged lower starting doses of eszopiclone.
- Liver processing: It is metabolized mainly by CYP3A4 (and to a lesser extent CYP2E1), so certain drugs can raise or lower its levels.
How Do Restoril and Lunesta Work for Sleep?
Both medicines calm the brain by boosting the effect of GABA, the brain’s main inhibitory chemical messenger, but they interact with GABA receptors differently. This section explains the shared mechanism and the differences.
The Shared Mechanism
GABA-A receptors act like a brake on nerve activity. Both drugs bind to a site on these receptors and make GABA’s calming signal stronger, which promotes drowsiness and sleep.
How Restoril Works
Temazepam, like other benzodiazepines, acts broadly across several GABA-A receptor types. That broad action explains why benzodiazepines also reduce anxiety, relax muscles and can prevent seizures. It tends to reduce time spent in deep (slow-wave) sleep and in REM sleep.
How Lunesta Works
Eszopiclone binds to the same general benzodiazepine-binding site but with a somewhat different pattern of subunit selectivity. It was designed to target sleep more specifically, with less muscle-relaxant and anti-anxiety effect than benzodiazepines. In practice, it still causes sedation, memory effects and dependence risk, so “non-benzodiazepine” does not mean “risk-free.”

Restoril vs. Lunesta for Insomnia: What Are They Used For?
Both treat insomnia, but the type of insomnia, the patient and the duration of need can influence which a clinician considers. This section explains their roles.
First-Line Treatment Comes First
Major guidelines, including those from the American College of Physicians and the American Academy of Sleep Medicine, recommend CBT-I as the first-line treatment for chronic insomnia. Medicines are generally added when CBT-I is unavailable, insufficient, or while it is being started.
Where Restoril Fits
Temazepam is mainly used for short-term insomnia, particularly when both falling and staying asleep are problems. It is an older, inexpensive medicine, but benzodiazepines are used cautiously because of dependence, falls and cognitive effects.
Where Lunesta Fits
Eszopiclone is used for sleep-onset and sleep-maintenance insomnia and has data supporting longer-term use than many hypnotics. It is also generally prescribed with caution, particularly for older adults and anyone with a history of sleepwalking or substance misuse.
What Neither Medicine Treats
Neither treats the cause of insomnia. Sleep apnea, restless legs syndrome, depression, anxiety, pain, caffeine, alcohol and shift work can all drive poor sleep, and a clinician may want to address these first.
How Long Do Restoril and Lunesta Take to Work?
Onset depends on the drug, the dose and whether you have eaten. These are general ranges, not guarantees.
Restoril Onset
Temazepam capsules are absorbed relatively slowly compared with some sleep drugs. Many people feel effects within roughly 30 to 60 minutes, and peak blood levels occur around 1 to 2 hours after a dose. Some prescribers advise taking it somewhat before the planned bedtime.
Lunesta Onset
Eszopiclone is absorbed quickly, with effects typically starting within about 30 minutes and peak levels around 1 hour. A high-fat or heavy meal taken right before or with the dose can slow absorption and delay the effect.
Practical Tips
- Take either medicine only when you can stay in bed for a full night (the labels advise about 7 to 8 hours).
- Do not take a dose in the middle of the night unless a prescriber has told you how and when to do so.
- Avoid driving, cooking or other activities after taking a dose.
Restoril vs. Lunesta: How Long Do Their Effects Last?
Duration of effect affects both sleep quality and next-day alertness. This section covers half-life and how long the effects can carry into the morning.
Restoril Duration
Temazepam has an intermediate half-life, averaging around 8 to 9 hours, with a wide range between people. It generally covers a full night but can leave some people drowsy or slowed the next morning, especially at higher doses or with age-related slower clearance.
Lunesta Duration
Eszopiclone has a half-life of roughly 6 hours in healthy adults, and longer in older adults. It usually covers most of a night, but morning impairment can still occur, particularly with a 3 mg dose or if you have less than a full night in bed.
Why Morning Impairment Matters
Both can affect driving and alertness the next day, and people are not always aware they are impaired. The FDA has highlighted this risk for the Z-drugs. If you feel foggy or sleepy the next day, tell your prescriber rather than driving or adjusting the dose yourself.
Dosage and Duration of Treatment
Doses below are for general understanding only. Your prescriber sets the dose based on age, health, other medicines and response.
Restoril Dosage
- Typical adult dose: 15 mg at bedtime, with a range of 7.5 mg to 30 mg depending on need and tolerance.
- Older or debilitated adults: The label advises starting at 7.5 mg.
- Duration: Intended for short-term use. Longer use raises the risk of tolerance, dependence and withdrawal.
Lunesta Dosage
- Typical adult starting dose: 1 mg at bedtime, which may be increased to 2 mg or 3 mg based on response.
- Older adults and certain conditions: A lower maximum dose, often 2 mg, applies. Dose limits also apply in severe liver impairment and with some interacting drugs.
- Duration: Reassess regularly. Long-term use should be a deliberate, monitored decision.
General Rules for Both
- Take exactly as prescribed, right before going to bed.
- Do not increase the dose because the medicine seems less effective, since that can signal developing tolerance.
- Do not stop suddenly after regular use. Ask about a taper.
- Do not share your prescription.
Common Side Effects of Restoril and Lunesta
Because both act on GABA receptors, they share many side effects, but each has some distinctive ones.
Shared Side Effects
- Drowsiness and next-day sedation
- Dizziness and lightheadedness
- Headache
- Impaired coordination
- Memory problems or confusion
- Nausea or stomach upset
- Dry mouth
More Often Reported With Restoril
- Fatigue and “hangover” feeling
- Muscle weakness
- Depressed mood in some users
More Often Reported With Lunesta
- Unpleasant or metallic taste, one of its most recognized side effects
- Dry mouth
- Rash or itching in some users
- Unusual dreams
When to Get Medical Help
Seek urgent medical care for trouble breathing, swelling of the face or throat, severe rash, new or worsening depression or suicidal thoughts, hallucinations, or episodes of sleepwalking or other behaviors you do not remember. Call emergency services for slowed or stopped breathing or if someone cannot be woken.
Serious Risks and Safety Considerations
Both medicines carry warnings that go beyond ordinary side effects. This section covers the most important ones.
Complex Sleep Behaviors
Sleepwalking, sleep driving, sleep eating, and making calls or having conversations while not fully awake have been reported, most notably with Z-drugs like Lunesta, and the FDA boxed warning applies to eszopiclone. Anyone who has experienced such an episode should stop the medicine and contact their prescriber.
Respiratory Depression and Opioids
Benzodiazepines such as temazepam carry a boxed warning that combining them with opioids can cause profound sedation, respiratory depression, coma and death. Alcohol and other sedatives add to the danger with both drugs.
Falls and Cognitive Effects in Older Adults
Sedative-hypnotics increase the risk of falls, fractures and confusion in older adults. The American Geriatrics Society Beers Criteria advises avoiding both benzodiazepines and Z-drugs in older adults in most circumstances.
Mental Health Effects
Both can worsen depression in some people, and sleep medicines can mask underlying conditions. Report mood changes or thoughts of self-harm right away.
Pregnancy and Breastfeeding
Benzodiazepines are generally avoided in pregnancy because of risks to the newborn, including sedation and withdrawal symptoms, and sleep medicines pass into breast milk. Anyone who is pregnant, planning pregnancy or breastfeeding should discuss options with a clinician.
Misuse and Overdose
Both have misuse potential. Overdose risk rises sharply when combined with alcohol or opioids. Keep medicine locked up and away from children, pets and visitors.
Restoril vs. Lunesta: Drug Interactions
Interactions are a leading source of harm with sleep medicines, so a full medication list matters. This section outlines the main ones.
Interactions Affecting Both
- Opioids: A serious risk of respiratory depression, coma and death.
- Alcohol: Increases sedation and impairment.
- Other CNS depressants: Other sleep aids, anxiety medicines, muscle relaxants, gabapentinoids, sedating antihistamines and some antipsychotics.
- Other benzodiazepines or Z-drugs: Taking more than one sleep medicine increases risk without a clear benefit.
Restoril-Specific Notes
Temazepam is cleared mostly through glucuronidation, so it is less affected by CYP enzyme inhibitors than many sedatives. It still needs caution with other sedating drugs.
Lunesta-Specific Notes
- CYP3A4 inhibitors (such as ketoconazole, itraconazole, clarithromycin, ritonavir) can raise eszopiclone levels, and a lower maximum dose is advised.
- CYP3A4 inducers (such as rifampin, carbamazepine, phenytoin, St. John’s wort) can lower levels and reduce effect.
- Olanzapine: Combined use has been associated with reduced psychomotor performance.
Check with a pharmacist before adding any prescription, over-the-counter product or supplement, including melatonin, antihistamine sleep aids and herbal products.
Dependence, Tolerance, and Withdrawal Risks
Both drugs can cause physical dependence, which is why they are designed for short-term or closely monitored use. This section explains the concepts and what withdrawal can involve.
Tolerance, Dependence and Addiction Are Different
- Tolerance: Needing more medicine for the same effect.
- Physical dependence: The body adapts, so stopping can cause withdrawal.
- Addiction (substance use disorder): Compulsive use despite harm. It can occur but is not inevitable.
Withdrawal From Restoril
Benzodiazepine withdrawal can include rebound insomnia, anxiety, irritability, tremor, sweating, headaches, muscle pain, and in severe cases seizures. Because seizure risk exists, abrupt discontinuation after regular use can be dangerous, and a gradual taper should be supervised by a clinician.
Withdrawal From Lunesta
Stopping eszopiclone after regular use can cause rebound insomnia, anxiety, nausea, tremor and, less commonly, more serious symptoms. A taper is usually recommended after longer use.
Rebound Insomnia
With either drug, sleep can temporarily become worse than before treatment after stopping. This is common and usually fades, but it can tempt people to restart the medicine. CBT-I skills can help during this period.
Getting Support
If you feel unable to stop, are taking more than prescribed, or are using sleep medicine with alcohol, help is available. In the US, the SAMHSA National Helpline offers free, confidential referrals 24/7. Elsewhere, your doctor or local health service can direct you.
Who Should Avoid Restoril or Lunesta?
Some people face higher risks and may need a different approach. This section lists common reasons for caution or avoidance.
Generally Avoided or Used Only With Specialist Guidance
- People taking opioids or heavy alcohol users
- Anyone with a history of sleepwalking or complex sleep behaviors (especially with Lunesta)
- Severe sleep apnea or other serious breathing conditions, since sedatives can worsen breathing
- Severe liver impairment (dose adjustments or avoidance)
- People with a history of substance use disorder
- Myasthenia gravis or narrow-angle glaucoma (for benzodiazepines such as temazepam)
- Known allergy to the drug or its ingredients
Groups Needing Extra Caution
- Older adults: Higher fall and confusion risk, so lower doses and often alternatives are advised.
- Pregnant or breastfeeding individuals: Discuss risks and alternatives first.
- People with depression or suicidal thoughts: Sleep medicines can complicate mood treatment.
- People who drive or work in safety-critical jobs: Next-day impairment matters.
Restoril vs. Lunesta: Which Sleep Medicine Is Right for You?
There is no universal answer, and neither is “better” in all situations. This section explains how clinicians think through the choice.
Factors a Clinician Considers
- Type of insomnia: Trouble falling asleep, staying asleep, or both
- Age and health: Older adults and people with breathing, liver or kidney issues need extra care
- Other medicines: Especially opioids, CYP-interacting drugs and other sedatives
- History: Substance use, sleepwalking, depression, previous reactions
- Duration of need: Short-term versus ongoing
- Lifestyle: Early-morning driving or work demands
- Cost and coverage: Both are available as generics
How They Compare in Practice
- Restoril may cover the night more fully for some people but can leave more morning sedation, and the benzodiazepine class carries well-known dependence and opioid warnings.
- Lunesta acts faster and is shorter-acting, but carries a boxed warning for complex sleep behaviors and can cause a bitter taste.
- Evidence suggests both help sleep modestly on average, and neither outperforms CBT-I over the long term.
Other Options a Clinician May Discuss
- CBT-I, often the best long-term option
- Orexin receptor antagonists (such as suvorexant, lemborexant, daridorexant)
- Low-dose doxepin for sleep maintenance
- Ramelteon, which targets melatonin receptors
- Treating underlying causes such as sleep apnea, pain or anxiety
- Sleep hygiene and schedule changes
Questions to Ask Your Healthcare Provider
- What is causing my insomnia, and could something else be treating it better?
- Is CBT-I available to me?
- Do my other medicines or health conditions make either option unsafe?
- How long should I take it, and what is the plan to stop?
- What should I do if I notice sleepwalking, memory gaps or morning grogginess?
Consult a licensed doctor or sleep specialist before choosing or changing a sleep medicine. If you use telehealth or online services, choose licensed providers who perform a proper assessment, and be wary of any seller offering controlled sleep medicines without a prescription.
Frequently Asked Questions About Restoril vs. Lunesta
Short, direct answers to the questions people ask most often.
What is the difference between Restoril and Lunesta?
Restoril (temazepam) is a benzodiazepine with an intermediate duration. Lunesta (eszopiclone) is a nonbenzodiazepine Z-drug that is shorter-acting. Both enhance GABA to promote sleep, and both are Schedule IV controlled substances.
Is Restoril or Lunesta better for insomnia?
Neither is better for everyone. The right choice depends on your type of insomnia, age, health, other medicines and risk factors. A clinician makes that judgment.
Which is safer, Restoril or Lunesta?
Both carry real risks. Restoril has benzodiazepine boxed warnings (opioids, misuse, dependence), and Lunesta has a boxed warning for complex sleep behaviors. Safety depends on the person and how the drug is used.
Which works faster?
Lunesta typically starts working within about 30 minutes. Restoril often takes longer, commonly 30 to 60 minutes or more.
Which lasts longer?
Restoril generally lasts longer, with an average half-life around 8 to 9 hours versus roughly 6 hours for Lunesta.
Which causes more next-day drowsiness?
Either can. Restoril’s longer duration may cause more morning grogginess in some people, while Lunesta, especially at 3 mg, has been linked to next-day impairment. Do not drive until you know how you respond.
Can you take Restoril and Lunesta together?
Not on your own. Combining two sleep medicines raises the risk of excessive sedation, breathing problems and complex sleep behaviors, without a well-established benefit.
Can you drink alcohol with either one?
No. Alcohol increases sedation and the risk of dangerous breathing suppression with both.
Are Restoril and Lunesta addictive?
Both can cause physical dependence and, in some people, addiction, particularly with higher doses, longer use or a history of substance misuse.
Can you stop taking them suddenly?
No. After regular use, stopping suddenly can cause rebound insomnia and withdrawal, and with Restoril (a benzodiazepine) can occasionally be dangerous. Ask for a taper plan.
Why does Lunesta leave a bad taste?
A bitter or metallic taste is a common effect of eszopiclone, thought to occur as the drug appears in saliva. It usually fades as the drug wears off.
Is there a non-drug treatment that works as well?
Yes. CBT-I is recommended as first-line treatment and often provides lasting benefits after medicines are stopped.
Conclusion
Restoril (temazepam) and Lunesta (eszopiclone) both help people with insomnia, but they differ in drug class, onset, duration and risk profile. Restoril is an intermediate-acting benzodiazepine intended for short-term use, and it carries warnings about opioids, misuse and dependence. Lunesta is a shorter-acting Z-drug with a boxed warning for complex sleep behaviors and a well-known metallic taste. Neither is automatically safer or better, and both can cause next-day impairment, dependence and dangerous interactions.
